Abstract

A device () for filtering plastic melt having an inlet valve (), an outlet valve () and a filter canister (), wherein a cavity () closable by means of a cover () is formed and into which a melt channel () opens. In the filter canister () there is arranged a plurality of filter cartridges (), which are each formed by a filter substrate () and a filter lattice (). The filter substrate () comprises a wall having openings, said wall defining an internal space (), which opens through an outlet () into a collection channel (). The filter lattice () covers the openings of the filter substrate (). The melt channel () is adjacent to the inlet valve () and may be brought into fluid communication with an outlet channel () via the inlet valve (). The collection channel () is adjacent to the outlet valve () and may be brought into fluid communication with an outlet channel () via the outlet valve (). The cover () fixes the filter lattices () onto the filter substrates ().
